  • Renting an "EC2" server VS buying one (for a start up in initial stages)

    - by krish p
    We are a small start up in the early stages and are working on a SaaS-based Rails product. Currently, we use EC2 for a small instance and have a need for another large/extra-large instance as we are beginning to deploy to the Cloud and get ready to release our "alpha" version. While EC2 was my choice for numerous reasons (reliability, accessibility - small team is geographically dispersed, maintainability, and things of that nature), it appears to be rather expensive. While the product will ultimately be deployed in the Cloud (be it EC2 or otherwise) and that experience would help the development team, would it make sense to purchase a physical server and stick it in the basement or bite the bullet and pay the price for EC2 (or other Cloud Providers)? While such decisions are driven by numerous factors, it would certainly help to get the thoughts of other folks who may have been in similar situations. Hence, the post. Thanks much!

  • Adding Thunderbird-stable repository gives "can't find signing_key_fingerprint" error

    - by EBV2010
    I'm trying to install Thunderbird 11 on Kubuntu 10.04. I was able to do it on the machine I'm working on. To get a clean process that I can roll out to other clients, I re-installed the machine and repeated the process. This is what I did (I've left out the sudo for clarity): add-apt-repository ppa:ubuntu-mozilla-security/ppa apt-get update add-apt-repository ppa:mozilla-team/thunderbird-stable The last one resulted in this error: Error: can't find signing_key_fingerprint at https://launchpad.net/api/1.0/~mozilla-team/+archive/thunderbird-stable The machine as it was before re-installation gave no such message. It was built from the same sources. Bottomline: I got Thunderbird 11.0 to run on Kubuntu 10.04 but after re-installation, adding the repository gives an error and won't add. Is there a way to solve the signing_key_fingerprint error?

  • Sendmail Alias for Nonlocal Email Account

    - by Mark Roddy
    I admin a server which is running a number of web applications for a software dev team (source control, bug tracking, etc). The server has sendmail running solely as a transport to the departmental email server over which I have no control. We have someone who is still in the department but no longer on the dev team so I need to configure the transport agent to redirect all outgoing email (which would be coming from these applications) to the person that has taken their place. I added an entry in /etc/aliases like such: [email protected]: [email protected] But when I run /etc/init.d/sendmail newaliases I get the following error: /etc/mail/aliases: line 32: [email protected]... cannot alias non-local names So clearly I'm doing something I shouldn't. Is there a way to get aliases to work with non-local names or alternatively is their a way to accomplish my goal of redirecting outgoing mail for this user to another one? Technical Specs if the matter: Ubuntu 6.06 sendmail 8.13 (ubuntu provided package)

  • How to set up a file server in a restricted corporate environment

    - by Emilio M Bumachar
    I work in a big corporation, and the disk space my team gets in the corporate file server is so low, I am considering turning my work PC into a file server. I ask this community for links to tutorials, software suggestions, and advice in general about how to set it up. My machine is an Intel Core2Duo E7500 @ 3GHz, 3 GB of RAM, Running Windows XP Service Pack 3. Upgrading, formatting or installing another OS is out of the question. But I do have Administrator priviledges on the PC, and I can install programs (at least for now). A lot of security software I don't even know about is and must remain installed. But I only need communication whithin the corporate network, which is not restricted. People have usernames (logins) on the corporate network, and I need to use them to restrict access. Simply put, I have a list of logins of team members, and only people in the list should access the files. I have about 150 GB of free disk space. I'm thinking of allocating 100 GB to the team's shared files. I plan monthly backups on machines of co-workers, same configuration. But automation of backups is a nice, unnecessary feature: it's totally acceptable for me to manually copy the contents to a different machine once a month. Uptime is important, as everyone would use these files in their daily work. I have experience as a python and C programmer, but no experience whatsoever as a sysadmin, and almost nothing of my programming experience is network programming. I'm a complete beginner in this. Thanks in advance for any help. EDIT I honestly appreciate all the warnings, I really do, but what I plan to make available is mostly stuff that now is solely on DVDs just for space reasons. It's 'daily work' to read them, but 'daily work write' files will remain on the corporate server. As for the importance of uptime, I think I overstated it: a few outages are OK, it's already an improvement over getting the DVDs. As for policy, my manager is kind of on my side, I will confirm that before making my move. As for getting more space through the proper channels, well, that was Plan A, and it's still on the table... But I don't have much hope. I'm not as "core businees" as I'd like.

  • Google Drive desktop client not updating existing files from other users

    - by cqm
    I've looked around and there doesn't really seem to be any troubleshooting information for the Google Drive desktop client. It all assumes you are using Google Docs on the web. Anyway, my team is trying to use Google Drive like Dropbox, where multiple people are editing files shared amongst them through the desktop, such as images. Dropbox is really good at noticing when a checksum for a file is changed, and syncing it. Google Drive's desktop client seems not to do this at all. Google Drive desktop client seems to only sync newly created files and not giving any notification at all that there is a modified version, it will never sync it, even though going online and opening that file will show the modified version. Is there any way to fix this? and the answer has nothing to do with proxy or firewall configurations. Team is using computers running OSX and Windows.

  • Linux - Block ssh users from accessing other machines on the network

    - by Sam
    I have set up a virtual machine on my network for uni project development. I have 6 team members and I don't want them to SSH in and start sniffing my network traffic. I already have set the firewall on my W7 pcs to ignore any connection attempts from the Virtual Machine, but would like to go a step further and not allow any network access from the VM to other machines on my network. Team members will be access the VM by SSH. The only external port forwarded is to vm:22. The VM is running in VirtualBox on a bridged network connection. Running latest Debian. If someone could tell me how to do this I would be much obliged.

  • How to show a warning message when entering a folder?

    - by Valter Henrique
    I don't know if this is possible, but, I have a folder which I would like to show some warning message when the user enters in it. In my case would say that the folder could be deleted without previous warning to save some disk space. I already create a file inside the folder with the warning message: WARNING! ########################################################################################################################################################## Please, be advised, that the folder /company-backup/amazon-s3 can be deleted without previous WARNING to save disk space as the INFRASTRUCTURE TEAM judge necessary. Best regards, Infrastructure Team. ########################################################################################################################################################### Is that possible ? Any idea ?

  • Repairing a TFS 2005 install or starting anew.

    - by Johan Buret
    Following : Installing Team Foundation Server on a shared database instance We did use a shared database instance setup for TFS 2005, and that was not a good idea, because of the Reporting Service dependency. The reporting instance on the server gives error code 404. What works now Basic source code control. We're able to check in and out source code. What doesn't work : Everything else, including : Opening and creating new team projects. Build automation. Internal bug tracking. Goal setup Having a fully working TFS install, and keeping the history. 1) A full install of TFS 2005 on the same server, but within its own database and reporting instance. 2) Using another server might be an option, but it's really not prefered Downtime should be minimum, my colleagues needs to be able to work on the source Readings I've read the MSDN page about moving/restoring TFS 2005, but I'm still unsure about what to do. Thanks in advance for help

  • meeting availability using iPhone/iOS calendars

    - by Jaymie
    Our management team all use iPhones with the built-in iOS calendar app. We're looking into getting Microsoft Exchange for everyone here, but that'll take us some weeks to plan and roll-out across the enterprise. In the meantime, I need to provide something so group meeting availability can be determined from those calendars. Google Calendar would be ideal ("find a time") if I could find a way to link to/export the iCloud calendars, but Apple don't seem to want to do that. I could ask the management team to recreate their events for the next few weeks in individual Google Calendars, but they won't want to do that and it's wasteful rekeying of data. Any suggestions you can provide will be gratefully received.

  • Postfix - searching emails (logstash, greylog or other solution)

    - by Yarik Dot
    We are currently having ~100 servers and all of them are using remote syslog, so we have aggregated all logs on one server. The most questioned problem from our support team is: Has an email from .... to ... been delivered? I'd like to give to our support team access to some logging tool and some guide for searching in logs. What would you have recommended me? Or, do you know any other alternatives to test? The problem of grepping logs is that there is not sender and recipient address on one line. So I supposed, there might by some aggregation by email id.

  • Sharepoint 2010 can't find domain users when granting permissions

    - by quani
    I'm trying to grant permissions to other people to view a SharePoint site but when granting permissions it uses "Check Names" and claims any user or group that is part of a domain does not exist. It does this if I try granting permissions to the team site or in central admin BUT if I try to add someone to Farm Administrators in Central admin then all of the sudden it can find all domain users. Why is it finding domain users in that one context but not others? It is supposed to be using NTLM authentication and has Windows configured as the authentication provider (And IIS is configured to use NTLM). What's even more strange is I enabled Anonymous Access for the team site which I thought would allow anyone to view it but others say they can't access it.

  • AD Local Admins without password sharing

    - by Cocoabean
    My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

  • SVN: Working with branches using the same working copy

    - by uXuf
    We've just moved to SVN from CVS. We have a small team and everyone checks in code on the trunk and we have never ever used branches for development. We each have directories on a remote dev server with the codebase checked out. Each developer works on their own sandbox with an associated URL to pull up the app in a browser (something like the setup here: Trade-offs of local vs remote development workflows for a web development team). I've decided that for my current project, I'll use a branch because it would span multiple releases. I've already cut a branch out, but I am using the same directory as the one originally checked out (i.e. for the trunk). Since it's the same directory (or working copy) for both the branch and the trunk, if for e.g. a bug pops up in the app I switch to the trunk and commit the change there, and then switch back to my branch for my project development. My questions are: Is this a sane way to work with branches? Are there any pitfalls that I need to be aware of? What would be the optimal way to work with branches if separate working copies are out of the question? I haven't had issues yet as I have just started doing this way but all the tutorials/books/blog posts I have seen about branching with SVN imply working with different working copies (or perhaps I haven't come across an explanation of mixed working copies in plain English). I just don't want to be sorry three months down the road when its time to integrate the branch back to the trunk.

  • Box Selection and Multi-Line Editing with VS 2010

    - by ScottGu
    This is the twenty-second in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. I’ve already covered some of the code editor improvements in the VS 2010 release.  In particular, I’ve blogged about the Code Intellisense Improvements, new Code Searching and Navigating Features, HTML, ASP.NET and JavaScript Snippet Support, and improved JavaScript Intellisense.  Today’s blog post covers a small, but nice, editor improvement with VS 2010 – the ability to use “Box Selection” when performing multi-line editing.  This can eliminate keystrokes and enables some slick editing scenarios. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Box Selection Box selection is a feature that has been in Visual Studio for awhile (although not many people knew about it).  It allows you to select a rectangular region of text within the code editor by holding down the Alt key while selecting the text region with the mouse.  With VS 2008 you could then copy or delete the selected text. VS 2010 now enables several more capabilities with box selection including: Text Insertion: Typing with box selection now allows you to insert new text into every selected line Paste/Replace: You can now paste the contents of one box selection into another and have the content flow correctly Zero-Length Boxes: You can now make a vertical selection zero characters wide to create a multi-line insert point for new or copied text These capabilities can be very useful in a variety of scenarios.  Some example scenarios: change access modifiers (private->public), adding comments to multiple lines, setting fields, or grouping multiple statements together. Great 3 Minute Box-Selection Video Demo Brittany Behrens from the Visual Studio Editor Team has an excellent 3 minute video that shows off a few cool VS 2010 multi-line code editing scenarios with box selection:   Watch it to learn a few ways you can use this new box selection capability to optimize your typing in VS 2010 even further: Hope this helps, Scott P.S. You can learn more about the VS Editor by following the Visual Studio Team Blog or by following @VSEditor on Twitter.

  • Are programmers bad testers?

    - by jhsowter
    I know this sounds a lot like other questions which have already being asked, but it is actually slightly different. It seems to be generally considered that programmers are not good at performing the role of testing an application. For example: Joel on Software - Top Five (Wrong) Reasons You Don't Have Testers (emphasis mine) Don't even think of trying to tell college CS graduates that they can come work for you, but "everyone has to do a stint in QA for a while before moving on to code". I've seen a lot of this. Programmers do not make good testers, and you'll lose a good programmer, who is a lot harder to replace. And in this question, one of the most popular answers says (again, my emphasis): Developers can be testers, but they shouldn't be testers. Developers tend to unintentionally/unconciously avoid to use the application in a way that might break it. That's because they wrote it and mostly test it in the way it should be used. So the question is are programmers bad at testing? What evidence or arguments are there to support this conclusion? Are programmers only bad at testing their own code? Is there any evidence to suggest that programmers are actually good at testing? What do I mean by "testing?" I do not mean unit testing or anything that is considered part of the methodology used by the software team to write software. I mean some kind of quality assurance method that is used after the code has been built and deployed to whatever that software team would call the "test environment."

  • Scoring/analysis of Subjective testing for skills assessment

    - by ChrisBint
    I am lucky in the sense that I have been given the opportunity to be a 'Technical Troubleshooter' for our offshore development team. While I am confident and capable of dealing with most issues, I have come across something that I am not. Based on initial discussions with various team members both on and offshore, a requirement for a 'repeatable, consistent' skills assessment has been identified. In my opinion, the best way to achieve this would be a combination of objective and subjective tests. The former normally being an initial online skills assessment on various subjects, for example General C#, WCF and MVC. The latter being a technical test where the candidate would need to solve various problems and (hopefully) explain the thought processes involved with the solution whilst doing so. Obviously, the first method is consistent, repeatable and extremely accurate. The second is always going to be subjective and based on the approach, the solution (or possibly not) and other factors. The 'scoring' of this is also going to be down to the experience and skills of the assessor and this is where my problem lies; The person that is expected to be the assessor initially (me) has no experience. The people that will ultimately continue this process for other people will never remain the same due to project constraints and internal reasons, this changes the baseline for comparison. I am not aware of any suitable system that can be classed as consistent and repeatable for subjective tests with the 2 factors above, let alone if those did not exist. So anyway, I have to present a plan that will ultimately generate a skills/gap analysis and it is unlikely that I will be able to use an objective method (budget constraints most likely reason). The only option left is the subjective methods and the issues above. Does anyone have any suggestions for an approach that may tick all the boxes?

  • Best of "The Moth" 2011

    - by Daniel Moth
    Once again (like in 2004, 2005, 2006, 2007, 2008, 2009, 2010) the time has come to wish you a Happy New Year and to share my favorite posts from the year we just left behind. 1. My first blog entry in January and last one in December were both about my Windows Phone app: Translator by Moth and Translator by Moth v2. In between, I shared a few code snippets for Windows Phone development including a watermark textbox, a scroll helper, an RTL helper and a network connectivity helper - there will be more coming in 2012. 2. Efficiently using Microsoft Office products is the hallmark of an efficient Program Manager (and not only), and I'll continue sharing tips on this blog in that area. An example from last year is tracking changes in SharePoint-hosted Word document. 3. Half-way through last year I moved from managing the parallel debugger team to managing the C++ AMP team (both of them in Visual Studio 11). That means I had to deprioritize sharing content on VS parallel debugging features (I promise to do that in 2012), and it also meant that I wrote a lot about C++ AMP. You'll need a few cups of coffee to go through all of it, and most of the links were aggregated on this single highly recommended post: Give a session on C++ AMP – here is how You can stay tuned for more by subscribing via one of the options on the left… Comments about this post by Daniel Moth welcome at the original blog.
